Description

Technical Field

[0001] This utility model relates to the field of oil pressing equipment technology, specifically to a continuous feeding oil pressing equipment. Background Technology

[0002] Currently, there are two main types of oil presses on the market: high-temperature screw presses and low-temperature hydraulic presses. High-temperature screw presses involve filling the hopper with oilseeds, then rotating the screw until all the oilseeds in the hopper are pressed. Low-temperature hydraulic presses, on the other hand, involve filling the pressing chamber with oilseeds, then the hydraulic cylinder directly compresses all the oilseeds in the pressing chamber.

[0003] Chinese patent document CN211683630U discloses an improved feeding device for an oil press, including a loading hopper. A feeding hopper is fixedly connected to the bottom of the loading hopper, and a limiting block is fixedly connected to the top of the feeding hopper. A first bearing is fixedly connected to one side of the limiting block, and a rotating rod is movably connected to the inner wall of the first bearing. A first rotating disk is fixedly connected to the outer wall of the rotating rod. This improved feeding device in the oil press facilitates feeding, greatly simplifying the process and preventing machine blockage caused by excessive feeding. It also provides effective protection for the internal parts of the oil press, extending its service life and improving its oil pressing efficiency. This solves the problem of inconvenient feeding in conventional oil presses, thus bringing great convenience to people's work and life.

[0004] In the above technical solution, the feeding hopper, limiting block, first bearing, rotating rod, first gear, second gear, rotating shaft and feeding blade are used in combination to achieve the purpose of convenient feeding of the oil press with the improved feeding device. However, if the raw materials for oil pressing are not completely screened, it will also affect the quality of the pressed oil. Utility Model Content

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figures 1-3 As shown, the oil pressing equipment with continuous feeding provided by this utility model mainly includes a tank body 1, an auger 2, a drive device 3, an air inlet 4, an inclined platform 5, an electric heating element 6, an air outlet 7, and a receiving bag 8.

[0023] The tank body 1 is generally cylindrical, and its axis is preferably set to slope downwards from left to right, with an angle between 5° and 15° with the horizontal plane, for example, 10°. This inclination angle facilitates the natural movement of materials towards the discharge port 12 under the pushing action of gravity and the auger 2. The feed port 11 is opened on the upper part of the left side wall of the tank body 1, and the discharge port 12 is opened on the lower part of the right side wall. The upper end of the feed port 11 is preferably extended into a funnel-shaped receiving trough to facilitate the receiving and guiding of oil crops (such as peanuts, rapeseed, soybeans, etc.) to be processed.

[0024] The auger 2 is coaxially arranged inside the tank body 1 and is the core component for material conveying and screening. The auger 2 includes a rotating hollow rotating shaft 21 and spiral drive blades 22 fixed around the outer wall of the rotating shaft 21. The rotating shaft 21 is supported on the left and right end walls of the tank body 1 by bearing seats. Specifically, the left side of the rotating shaft 21 constitutes the rotating end, which is radially fixed and rotatable by bearings; the right side constitutes the fixed end, which is connected to the feed inlet 11. To ensure the sealing of the rotating parts and prevent material leakage, the bearings used at the fixed end and the rotating end are preferably sealed bearings.

[0025] The rotating shaft 21 has a plurality of filter holes 23 evenly distributed on its tube wall. The diameter of these filter holes 23 is larger than the size of normal oil particles (for example, the diameter can be 1-3 mm), and the diameter of the filter holes 23 is smaller than the diameter of other impurities, such as weeds. Therefore, the entire hollow rotating shaft 21 constitutes a dynamic filter screen.

[0026] The outer peripheral edge of the drive blade 22 has a very small gap or slight contact with the inner wall of the tank 1. In order to achieve good sealing and wear resistance, the outer peripheral edge of the drive blade 22 can be inlaid or made entirely of elastic wear-resistant materials such as hard rubber and polyurethane. This design can effectively scrape the inner wall of the tank 1 to prevent material adhesion, and can also form a basic seal between the drive blade 22 and the inner wall of the tank 1 to ensure that the material is pushed forward stably.

[0027] The drive device 3 is used to drive the auger 2 to rotate. In this embodiment, the drive device 3 is preferably a drive motor, which is fixedly installed on the outside of the right side of the tank 1 by a bracket. The output shaft of the drive motor is directly connected to the rotating end of the rotating shaft 21 through a coupling, thereby transmitting power to the auger 2.

[0028] The top of the tank 1 has multiple air inlets 4 evenly distributed along its axial direction. These air inlets 4 can be connected to an external hot air source (such as a hot air furnace or electric heater). To further optimize the hot air distribution, the axis of the air inlets 4 is preferably set to be inclined from left to right, with an angle of 10° to 30° with the vertical normal direction of the top of the tank 1, so that the hot air direction and the material movement direction intersect to a certain extent, thereby improving drying efficiency.

[0029] Multiple heating elements 6 are also provided on the inner wall of the tank 1. These heating elements 6 can be in the form of strips or sheets, and are distributed circumferentially or axially along the inner wall of the tank 1 to assist in heating and perform secondary drying of the raw materials in the tank to remove excess moisture.

[0030] The inclined platform 5 is located on the bottom inner side of the feed inlet 11. It is a guide plate that extends from the left inner wall of the feed inlet 11 to the right and gradually slopes upward. The lower end of the inclined platform 5 is connected to the bottom of the feed inlet 11, and the higher end is smoothly connected to the right inner wall of the rotating shaft 21 (filter screen). Its inclination angle allows the material falling from the feed inlet 11 to be guided to the bottom area of ​​the filter screen.

[0031] An air outlet 7 is provided on the end wall of the tank body 1 corresponding to the right end of the rotating shaft 21 (filter). The air outlet 7 is connected to the receiving bag 8. Dust, light impurities and other substances that enter the interior of the rotating shaft 21 through the filter holes 23 can be discharged from the air outlet 7 with a small amount of airflow and collected in the receiving bag 8.

[0032] The working principle of this utility model is as follows: Feeding and preliminary screening: Start the drive unit 3 (drive motor) to drive the auger 2 to rotate slowly (speed for example, 10-30 rpm), and pour the oil to be processed into the funnel at the top of the feed inlet 11. After the material falls into the tank 1, it first falls on the inclined platform 5, and under the push of the spiral drive blades 22 of the auger 2, it moves to the right (i.e., towards the discharge port 12) along the downward inclined tank 1. During this process, the material is wrapped around the outside of the rotating shaft 21, which acts as a filter screen, and enters the hollow rotating shaft 21 through the filter holes 23, thus realizing continuous screening of the material.

[0033] Drying process: External hot air is sent into the tank 1 through the air inlet 4. At the same time, the electric heating element 6 on the inner wall of the tank works to generate heat. The hot air and electric heat work together to heat and dry the material being conveyed and screened, effectively reducing the moisture content of the material. The inclined air inlet 4 allows the hot air to come into more full contact with the material, resulting in uniform drying.

[0034] Impurity collection and discharge: Impurities entering the interior of the rotating shaft 21 are carried by a small amount of airflow and eventually discharged through the air outlet 7 at the right end of the rotating shaft 21. They are captured by the receiving bag 8. After screening and drying, the clean and dry material is continuously pushed by the auger 2 to the discharge port 12 at the right end of the tank 1. After discharge, it can enter the subsequent pressing process.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
